EVAPORATlNG PAN FOR HOT-AIR FURNACES.

SPECIFICATION forming part of Letters Patent No. 385,716. dated July 10, 1888.

Application filed November 1'7, 1936. Serial No. 219,131. (No model.) 7

To all whom it may concern.-

Be it known that I, FRANCIS KERNAN. J12, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Ii'nprovemcnts in I lvaporating-Pans for HotAir Furnaces; and I do hereby declare that the following is a full,-clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to an improvement in an evaporating-pan connected with a hot air furnace; and it consists in the mechanism hereinafter pointed out and claimed.

In the accompanying drawings, Figure 1 represents a side view of an ordinary hotair furnace ineloscd, the broken line indicating a portion of the housing removed, showing the evaporating-pan in section. Fig. 2 represents a perspective view of the evaporating-pan, the dotted line representing the movement of the swinging door. Fig. 3 represents the same view as Fig. l, with a swinging door closed.

Heretofore evaporating-pans have usually been employed so constructed as to require the pan to be drawn out or removed from the furnace, in order to fill the same with water. This is a serious objection, as the pans are necessarily heavy and cumbersome, requiring considerable strength to operate them. this reason their use has been substantially abandoned,to the detriment of the furniture in houses heated with hot-air furnaces,and to the health of the occupants. In other cases sta tionary reservoirs or pans have been provided inside of the shell or casing for receiving water, requiring the operator to open doors to fill the reservoir or tank at great inconvenience. I overcome these several objections by providing evaporatingpan 1, open at the top, provided at the front with projecting flange 2, for lapping the opening in the wall or casing of the furnace, the flange or front forming an inclosure for the opening. On the front of the evaporating'pau I provide a projection, 3, open at the top, which formsa projecting lip extending beyond the periphery or contour of the furnaceinclosure, the lip being For open at the top for receiving and conducting the water into the evaporating pan, and, indeed, forms a part of the pan. The top of the opening outside of the flange is opened or closed with swinging door 4, pivoted at 5 to an car on the pan, and is opened or closed by swinging the same on the pivot, as shown in Fig. 2, thus enabling the operator of the furtrace to fill the evaporating-pan with water without removing the same by opening the door pivoted on the projecting lip.

In the drawings, 6 represents an ordinary fire pot. The evaporating pan is held substantially horizontal by flange 2, surrounding the front of the evaporating pan by its con tact with the furnace-casing, by the employ ment of inclined catches 9, Fig. 3, on the nnder side of the pan. The spaces between the catches and the flange are sufficient to admit the furnace-easing, or the frame surrounding the opening in the furnacecasing between them. By this construction the evaporatingpan is held substantially horizontal, and care should be taken to so apportion the size of the pan as to prevent its coming in contact with the fire-pot. An air-space should be allowed between the end of the pan and the fire-pot.

7 represents the casing or furnace-jacket, forming air space 8 between the jacket and the furnace proper to accomodate the movement of the heated air.

10 represents a frame surrounding the opening attached to the outer surface of the jacket or casing of the furnace, forming substantially a door frame.

The important feature of my invention consists in forming the evaporating pan in such manner as to be easily removable, and to be held, when in position, substantially horizontal, leaving an air-space between the tire pot and the back of the evaporatingpain, and rendering it impossible to bring the evaporatingpan in contact with the furnace,and to provide means for filling the evaporating pan with water without disturbing the pan itself.

Another advantage of my invention consists in obviating the necessity and expense of fitting doors in the jacket or casing of the furnace.
